IMPROVEMENT IN LAMPS.

Specification forming part of Letters Patent No. 167,128, dated August24, 1875, application filed August 12, 1875.

OAsE B.

To all whom it may concern:

Be it known that I, BENNETT B. SC NEIDER, of the city, county, and Stateof New York, have invented a new and useful Improvement in Lamps; and Ido hereby declare that the following is a full, clear, and exactdescription of the same, reference being bad to the accompanyingdrawing, which'forms part of this specification.

This invention relates to that kind of lamp which has an oil-reservoirwith a valve in the bottom, and is placed in a case or receiver, inwhich it is supported at a level higher than the burner. This reservoiris made removable, and so that when taken out of its receiver andinverted it may be filled with oil through its valve, and when turnedtop side up again and inserted to its place in the receiver the latteris supplied with oil through the valve in the reservoir. The inventionconsists in a combination of a catch applied tolock the reservoir wheninserted to its place in the receiver, and a spring-valve applied to thebottom of the reservoir, whereby, on liberating the catch to remove thereservoir, said valve is automatically closed to prevent the escape ofoil from the reservoir when drawing the latter out from the receiver,and whereby, when the reservoir is inserted to its place in the receiverand locked by the catch, the valve is automatically opened to supply thereceiver with oil.

In the accompanying drawing, Figures 1 and 2 represent partly brokensectional elevations of a lamp-reservoir and receiver in differentpositions as regards the reservoir, valve, and catch. Fig. 3 is atransverse section on the line a: a.

A is the receiver, which connects with the wick-tube of the lamp by anoutlet, b. The receiver A may be of cylindrical construction, andreceives freely down within it the reservoir B, which is withdrawn andinverted for filling through an opening covered by a valve, 0, in itsbottom. This valve, which may be a simple disk, or of any other suitableconsiruction, has its closing action controlled by a -springas, forinstance, by a spiral spring, 0, arranged around an inner or back stemof the valve, and bearing at its one end against a bridge in thereservoir, so that in commencing to withdraw the reservoir from thereceiver the valve is automatically closed, and

kept tightly shut till purposely opened after the removed reservoir hasbeen inverted for filling. The filling may be effected by inserting thespout of a filling-can down within an overflow cup, 01, outside of thevalve, and pressing the same against the valve, so as to open it. Thevalve 0 is automatically opened, when the reservoir is inserted to itsplace within the receiver, by causing the valve to come in contact withthe receiver A-a-s, for instance, either by an outer extension of thevalve striking the bottom of the receiver, as shown in the drawing, orby the face of the valve striking a fixed stem or projection within thereceiver. This automatic opening and closing of the valve, however, issubject to the control of a catch applied to lock the reservoir when inplace within the receiver, with the valve in the reservoir open, but sothat when said catch is liberated to remove the reservoir the "alve isautomatically closed, to prevent the escape of oil from the reservoirwhen drawing the latter out from the receiver.

This catch may be variously constructed and applied. Thus, it may eitherbe a springcatch or any other catch, and the male portion of it eitherbe on the reservoir or on the receiver, and the female portion tocorrespond but, for the purpose of illustration, a springcatch, or maleportion D thereof, is here shown as applied to the receiver A, and sothat the same is operative from the exterior of the receiver, toautomatically lock with the reservoir by overlapping a circular rib, f,on the reservoir when the latter is down to its place, but so that whensaid catch is withdrawn the reservoir B is free to be drawn up or to bethrown up by the valve-spring, and the valve closed, as clearly shown inFig. 2 of the drawing, after which the reservoir having the valve closedmay be wholly removed from the receiver.

I claim The combination of a catch applied to lock the reservoir wheninserted to its place in the receiver, and a spring-valve applied to thebottom of the reservoir, substantially as specified.
